GOAL-STOVE.

TO ALL PERSONS TO WHOM THESE PRESENTS SHALL G OME Be it known that I, JOIIN L. HANSON, oi Boston, in the county of Suffolk, and State of Massachusetts, ha e invented a new and useful improvement in Stoves; and do hereby declare the same to be fully described inthe following specification, and represented in the accompanying drawings, of which- Figure 1 is a side elevation.

' Figure 2, a vertical and longitudinal section, and

Figure 3 a vertical and transverse section of it.

Figure 4 is a horizontal section, taken through the middle of it.

Figure 5 is a horizontal section of the flue-space for warming the oven.

Figure 6 is an under-side view of the oven.

The fuel-chamber A of this stove is a close chamber provided with a threat, a, and a door, 6, thereto. Within the said chamber is a movable horizontal partition, 0, supported on brackets old, and made with an elongated hole, 0, to receive a rotary grate,f. A fiange, g, is raised on the partition 0 around the grate, and there is also a back or lining-guard or curved plate, It, raised on such partition in manner as represented in the drawings. The guard 72 is for supporting a fire-proof lining of'fire-brick or fiie-iilay, when built up on the partition and around the grate. It is'intended that the partition, with its grate and adjuncts, as described, may

be removable from the fire-chamber, in case it may be desirable to have wood rather than coal therein. The

partition and the grate areto enable coal to be burned in the fire-chamber, the space thereof under the partition serving as a receiver of ashes which mayfall from the grate. At its upper part and opposite sides the fireehamber A opens into two small and narrow chambers, B O. A damper, D, is arranged in the chamber 0, or applied thereto so as to enable aperson by moving the said damper either to open. or close communication between the fire-chamber and an escape-flue, E, or between, the said fire-place and a. series of pipes, F F F, leading downward from and vertically out of the chamber C, and into aflue-spaoe, G, which nearly encompasses the lower part of the fire-chamber A. This flue-space is shown more particularly in fig. 7, which is ahorizontal section of thestove, such section being taken through the said flue-space. Another series of pipes, F F F,

leads out of the chamber 13, and down therefrom into the flue-space G. Furthermore, there is a series of pipes, H H, &e., leading upward from the space G and about the fire-chamber A, and opening into an oven flue-space or chamber,-1, formed in the upper part of the stove. The oven shown at K is in the form of an elongated disk, provided with a cover, 2'. Flanges I: Z on 12 extend down from the perimeter of the bottom of the oven, so

as to touch the bottomeof the fiue-spaee I, there being a narrow space, a, between the bottom of such space I and that of the oven. These flanges, with the openings 0 g r between them, and with the vertical partitions g r, cause the heat and smoke discharged from the pipes H H to circulate freely and fully around the sides and underneath the oven, and to escape down through a hole, 8, leading from such space I into the chamber C. The said partitions q r are represented in fig. 5. They extend from the sides ofthe chamber I to the oven. The said even may have a hole through its bottom, such hole being provided with a cover, m. The said hole is to enable a person to insert the bottom of" a tea-kettle into or expose it to the flame-space I, for the purpose of being hehted by the smoke when coursing through such, or by the top plate of the fire-chamber. Through the top of each of the chambers B dis a series of holes, tt, there being one of them directly over each ,of the vertical pipes leading out of the said chambers. These holes oppn out of the flue-space I, and are there provided with covers 2'4 u. Their purpose is to enable either of the dues or pipes to be cleaned out by a rod run down into it and through the hole over it. The external case a of the stove has openings, 20 w, in front of each series of vertical pipes, such openings having woven wire guards, at 2:, inserted in them. Furthermore, there are passages, yy, leading up through the bottom plate of the stove and into the pipe-chamber .2 which encompasses the fire-plumber A. The said openings serve to supply the pipe-chamber with air. The heat radiated from the'vertical pipes and the walls of'the fire-chamber will be discharged through the wire guards.

In the operation of the stove, the smoke from the firechan1ber A will pass intothe two'chambers B O; the

damper being raised into its highestposition, the smoke will enter and flow through the pipes F F. leading down from the said two chambers, thence it will pass into the space G, thence up the several pipes H, and into and through the flue-spaco I and about the oven, thence through the hole 8 and into the discharge flue E! On.

depressing the damper the smoke will pass from the fire-place directly into the flue]? without first going through the pipes F F.

In the said stove, I claim as my invention the following, viz v I claim the combination as well as the arrangement of the fire-chamber A, the two chambers B C the descending pipes F F, the flue-space G, the ascending pipes H H, their chamber z, and the oven flue-space or chamber I, and its escape-flue or passage. I

I also claim the combination and arrangement of the flanges 7c int n with the dished oven, or with the same, the flue-space I, the series'of pipes H, the flue-space G, the pipes F F, the chambers B C, and the fire-chamber A.

I also claim the combination as well as the arrangement, of the series of holes t t and their covers, as set forth, with the fiuespace I, the pipes H F F, the flue-space G, and the chambers A B C.

I also claim the combination, as well as the arrangement, of the passagesy y, the flue-space Gr, the chambers A B C, the pipes H F F, the flue-space I, and the chamber z, the whole being substantially as hereinbetore explained.

I also claim the combination, as well as the arrangement, of the flange g and the lining guard h with the grate-holding partition 0, made with a hole through it to receive a grate, as specified.
